In an era of globalization, incumbents face strong incentives to attribute poor economic performance to external actors. While motivated reasoning explains how partisans update blame toward domestic incumbents, it remains unclear whether such blame is genuinely redirected to external actors beyond voters’ political control. Moreover, externalizing blame may signal limits to democratic accountability, with potential consequences for democratic belief. This article advances an asymmetric blame-shifting argument and tests it with two pre-registered survey experiments conducted on Amazon MTurk following the 2022 US midterm elections (n = 802; n = 999). Exploiting President Joe Biden’s attribution of rising inflation to Vladimir Putin, the experiments show that blame-shifting cues polarize partisan evaluations of the domestic incumbent: Democrats reduce blame toward Biden, while Republicans intensify it. In contrast, blame attribution toward the external actor remains largely unchanged across both studies. Study 2 further provides limited but suggestive evidence that exposure to external blame narratives may weaken democratic belief among opposition partisans. Together, the findings indicate that elite blame-shifting operates asymmetrically, which intensifies domestic partisan polarization without redistributing blame across borders, and such asymmetry may further erode democratic legitimacy.
